PROBLEM TO BE SOLVED: To achieve production of a hyper micronized cosmetic substrate until the lava stone around Mt. Fuji as a source of mineral extract becomes particles with an average particle diameter of about 50 nanometers, and to provide a method for producing cosmetics (particularly, various viscosity liquid cosmetics, such as a skin lotion and an essence) containing mineral ingredient which is dispersed homogeneously enough and is changed into colloidal state by combining liquid state various cosmetics with it mainly.SOLUTION: The cosmetic substrate contains the lava stone used for the substrate for cosmetics by making a lava colloidal state with lava powders and a solvent, while making the lava powders at least with a particle diameter of 0.2 &mum or less from the pulverized lava stone.
